What is a continuous passive motion unit?

• A piece of equipment that moves the pt passively with the intent to inc or maintain motion

• Typically applied 4-6 hrs a day for 1-4 weeks after surgery

What are the indication for CPM?

• To inc ROM (used mainly on knees after TKA, ACL reconstruction, or tibial plateau fx)

• Prevention of post-surgical stiffness

What are some of the benefits of using CPM?

• Prevents development of adhesions and contractures that cause

joint stiffness

• Provides a stimulating effect on the healing of tendons and

ligaments

• Enhances healing of incisions over the moving joint

• Increases synovial fluid lubrication of the joint and thus increases

the rate of intra-articular cartilage healing and regeneration

• Prevents the degrading effects of immobilization

• Provides a quicker return of ROM

• Decreases postoperative pain

What are contraindications for using CPM?

• DVT

• Active bleeding

• Opening incisions

• Movement past the ROM limitation indicated in the POC

What are precautions for using CPM?

• Impaired mentation

• Movement that is limited by other body parts (such as the stomach)

• Impaired sensation

What are potential adverse effects of using CPM?

• Increased bleeding inside the joint
